[Operation of electronic device]
The operation of the electronic device 10 according to the first embodiment will be described with reference to FIG.
First, in step S11, the IC 12A sequentially scans the sensing units SE1 to SE7, acquires detection signals S1 to S7 of the sensing units SE1 to SE7, and supplies the detection signals S1 to S7 to the CPU 12B.

Next, in step S12, the CPU 12B determines whether at least one of the detection signals S1 to S7 supplied from the IC 12A exceeds the threshold value -B. The threshold value -B is opposite in polarity to the threshold value A for determining the pressing of the buttons BT1, BT2 and BT3 at the prescribed pressing position. If it is determined in step S12 that at least one of the detection signals S1 to S7 exceeds the threshold -B (see FIGS. 9B and 10B), the CPU 12B sends the electronic device 10 to the electronic device 10 in step S13. It is determined that bending or twisting (see FIGS. 9A and 10A) is applied. Then, in step S14, the CPU 12B displays a screen (see FIG. 13A) for warning the user that bending or twisting is applied to the electronic device 10 on the display device 13A, and returns the process to step S11. The image data relating to the warning screen is stored in the storage unit 68, and the image data is read by the CPU 12B and displayed on the display device 13A.

If it is determined in step S12 that at least one of the detection signals S1 to S7 does not exceed the threshold value -B, the CPU 12B selects one of the detection signals S1 to S7 supplied from the IC 12A in step S15. It is determined whether or not at least one signal of the signal A exceeds the threshold A.

When it is determined in step S15 that at least one of the detection signals S1 to S7 exceeds the threshold A, the CPU 12B determines that the signal level of the detection signals exceeding the threshold A is the highest in step S16. It is determined whether the high detection signal corresponds to any one of the sensing units SE2, SE4, and SE6 (that is, the buttons BT1, BT2, and BT3). If it is determined in step S15 that at least one of the detection signals S1 to S7 does not exceed the threshold A, the CPU 12B returns the process to step S11.

If it is determined in step S16 that the detection signal with the highest signal level corresponds to any of the sensing units SE2, SE4, and SE6 (see FIG. 8B), the CPU 12B performs sensing in step S17. The processing corresponding to the sensing unit SE (see FIG. 8A) in which the detection signal having the highest signal level is detected among the units SE2, SE4, and SE6 is executed.

If it is determined in step S16 that the detection signal with the highest signal level does not correspond to any of the sensing units SE2, SE4, and SE6 (see FIG. 11B), the CPU 12B determines in step S18 that It is determined that the position not pressed, specifically, the corresponding position between the buttons BT1 and BT2 or the buttons BT2 and BT3 is pressed (see FIG. 11A). Then, in step S19, the CPU 12B warns the user that the prescribed position is not pressed, specifically, between the buttons BT1 and BT2 or between the buttons BT2 and BT3 (see FIG. 13B). ) Is displayed, and the process returns to step S11. The image data relating to the warning screen is stored in the storage unit 68, and the image data is read by the CPU 12B and displayed on the display device 13A.

Even when a twist is applied to the electronic device 10, the wall 14C facing the side wall 11R via the groove 14 deforms toward the side wall 11R. Therefore, the CPU 12B can also determine that a twist is applied to the electronic device 10, as in the case where the bottom 11M is pressed.

When any of the buttons BT1, BT2 and BT3 is pressed, the sensing surface 20S of the sensor 20 is pressed via the convex portion 26. As a result, in the IC 12A, an increase in the detection signals S2, S4, and S6 is detected in each of the sensing units SE2, SE4, and SE6 for detecting a user operation. Therefore, the CPU 12B determines whether or not there is a signal exceeding the threshold A among the detection signals S1 to S7, and which of the sensing units SE2, SE4, and SE6 is a signal exceeding the threshold A. , And pressing of the buttons BT1, BT2, and BT3 can be detected.

The electrode 35 has a shape in which rectangular corners are cut off in a straight line. The cutting angle θ is, for example, 45 degrees. The shape of the electrode 35 is not limited to this, and it may be a shape in which corner portions of a rectangle have an R shape, a polygonal shape such as a rectangular shape, a circular shape, an elliptical shape, or an irregular shape.

The sensor electrode layer 30A also includes a plurality of wires 35A that electrically connect the electrodes 45 to the connector 42. In the self-capacitance sensor electrode layer 30A, the wiring 35A is necessary for the number of sensing portions SE to be individually detected, that is, the number of electrodes (detection electrodes) 35 for detecting a capacitance change.

The wiring 35A drawn at a right angle to the side of the electrode 35 may be bent at a right angle to change the direction, but as shown in FIG. It is preferable that it is changed. This is because changes in the width of the wiring 35A can be suppressed, and the generation of noise can be suppressed. In addition, also in portions other than the above, it is preferable that the direction is not changed by bending the wiring 35A at right angles, but the direction is changed by being bent twice at an angle of 45 degrees.

In the self-capacitance system, the IC 12A detects the proximity of the metal layer 21 by the change in capacitance from each electrode 35. The sensor 20 can also be regarded as one type of capacitor whose shape changes with pressure. In the IC 12A, the proximity of the metal layer (ground electrode) 21 to the electrode (detection electrode) 35 is detected as an increase in the capacitance of the electrode 35. The amount of change in capacitance of the sensor 20 with respect to the pressure on the sensing surface 20S can be easily adjusted based on the distance between the metal layer 21 as the ground electrode and the electrode 35 as the detection electrode and the dielectric constant, the area of the electrode 35, etc. Can. When the multi-touch can be detected by the sensor 20, it is preferable to use a mutual capacitive sensor as the sensor 20.
